The version mismatch is related to the different versions upstream. Collabora uses collaboraoffice package version 6.0 , while their meta package (which also includes the document management loolwsd) is version 4. The app package version should reflect the version of the meta package, in this case 3.4.0

We have explicitly made email status notifications sticky until resolved. We have done that, since most apps are able to send out emails and thus those mails would always end up in spam or right out get denied by the receiving email server if those things are not setup. So in your case you don't care about such emails being lost? If there are good reasons to not nag the user about those issues, we can add some "ignore" setting I guess. Maybe you can describe your use-case about this a bit further.
